New benchmark aims to break 4pm fix hegemony

Siren uses 20-minute trade window in a bid to combat fears of manipulation

A new upstart has joined the foreign exchange benchmark fold. Siren, which began trading in January, is hoping to challenge the iron grip that the WM/Refinitiv 4pm fix has on the spot market.
